setup AFNetworking 3.x singleton Request and Response serialization

Question

Hi i'm using AFNetworking 3.x. I have built a singleton for network api

+ (ApiClient *)sharedInstance {
    static ApiClient *sharedInstance = nil;
    static dispatch_once_t oncePredicate;
    dispatch_once(&oncePredicate, ^{
        NSURLSessionConfiguration *sessionConfiguration = [NSURLSessionConfiguration defaultSessionConfiguration];
        sharedInstance = [[self alloc] initWithBaseURL:[NSURL URLWithString:SINGPOST_BASE_URL] sessionConfiguration:sessionConfiguration];

    return sharedInstance;
}

- (id)initWithBaseURL:(NSURL *)url
{
    if ((self = [super initWithBaseURL:url])) {
        AFJSONRequestSerializer *serializer = [AFJSONRequestSerializer serializer];
        [serializer setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
        [serializer setValue:@"application/json" forHTTPHeaderField:@"Accept"];
    }

    return self;
}

i want to setup the Request and Response Serialisation when using the singleton. How can we do that

I write these code keep getting error. any help is much appreciate. Thanks

[[[ApiClient sharedInstance]requestSerializer = [AFHTTPRequestSerializer] requestWithMethod:POST_METHOD URLString:urlString parameters:xml error:nil]];

my response serialization

ApiClient sharedInstance].responseSerializer.acceptableContentTypes = [[ApiClient sharedInstance].responseSerializer.acceptableContentTypes setByAddingObject:@"text/html"];

You need change your call [AFHTTPRequestSerializer requestWithMethod..] to

[[AFHTTPRequestSerializer serializer] requestWithMethod:POST_METHOD URLString:urlString parameters:xml error:nil];

AFHTTPRequestSerializer don't have a class method requestWithMethod it need the first create a instance and after call requestWithMethod

Your code will look like:

[[ApiClient sharedInstance] requestSerializer] = [[AFHTTPRequestSerializer serializer] requestWithMethod:POST_METHOD URLString:urlString parameters:xml error:nil];
